Make it in a slow cooker
You can use a slow cooker for this, making up the whole recipe then leaving it to cook through on Low for 6 hours.
Whizz the onion, breadcrumbs and parsley in a food processor until finely chopped. Add the mince, nutmeg and seasoning. Use the pulse button to mix but don’t overdo it or you’ll make a paste. Form into 20 walnut-sized meatballs and dust with flour.
Heat the oil in a large frying pan and fry the meatballs in batches until they are browned all over, then carefully lift them out with a slotted spoon and drain them on kitchen paper.
Melt the butter in the pan, then sprinkle over the flour and stir well. Cook for 2 mins, then slowly whisk in the stock. Keep whisking until it is a thick gravy, then return the meatballs to the pan and cook them for 5 mins. Stir in the cream. Before serving, check one to see if they are cooked all the way through to the centre.
